Abstract
A thermostat for the memory alloy driving of a vehicle engine system consists of a main valve, a shell, a valve rod and an assistant valve and is characterized in that the inside of the shell is equipped with a memory spring sleeved on the upper end of the valve rod. One end of the memory spring is the main valve, and the other end is a spring base connected with the shell by an arm rod. The outside of the shell is equipped with a bias spring sleeved on the lower end of the valve rod. The two ends of the bias spring are the spring base and the assistant valve respectively. With the change of the water temperature and the mating of the two springs, the utility model controls the opening of the main valve so as to assure an internal combustion engine to always operate under the best temperature condition and has the advantages of a simple structure and a reliable performance.
Description
Technical field:
The utility model relates to a kind of valve body, particularly a kind of thermostat that is used for automobile engine system.
Background technique:
Thermostat is the parts in the motor car engine, and its function is the temperature of regulating the engine cycles cooling water, often works in the best condition to guarantee internal-combustion engine.
Commonly used is waxtype thermostat at present, and temperature sensing material is extraordinary paraffin, leans on the different condensing temperature of paraffin to open the main valve of thermostat, makes cooling water flow through radiator heat-dissipation.The circulation of radiator of flowing through claims major cycle again, otherwise claims short circle, and the water temperature of cooling water is regulated by thermostat, and the heat of the hot parts water that is cooled is taken away, and sheds by radiator, and internal-combustion engine just can not be overheated.The shortcoming of waxtype thermostat is a complex structure, the manufacture process requirement height, and easily leak, cause thermostat to lose efficacy, device is changed frequent.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of simple in structure, the memory alloy driven thermostat of reliable performance.
The utility model purpose is to realize like this, it includes main valve, housing, valve rod, secondary valve, it is characterized in that: enclosure interior is equiped with the memory spring that is placed on the valve rod upper end, and the two ends of this memory spring are respectively main valve and the spring seat that links to each other with housing by armed lever; Outside is equiped with the bias spring that is placed on the valve rod lower end, and these bias spring two ends are respectively spring seat and secondary valve.Memory spring uses shape memory alloy material.Marmem forms fixing memory temperature, just its refresh memory temperature that can design.After marmem surpassed setting temperature, refresh memory made thermostat be in open mode, causes the circulatory system to enter major cycle, allows water enter radiator and cools off, and makes motor keep normal working state.
The utility model has the advantages that and utilize two compressible spring to change the labyrinth of waxtype thermostat in the past; Because the setting temperature of memory spring is adjustable and more accurate, thereby has better solved the coarse problem of waxtype thermostat; Memory alloy spring can more times use that moves in circles, and the life-span of thermostat is obviously improved, and has changed waxtype thermostat because the life-span that leakage caused of paraffin reduces.
Description of drawings:
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, so that above-mentioned purpose of the present utility model and advantage are more prone to be understood.
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
As shown in the figure, the utility model mainly is made up of main valve 1, housing 2, valve rod 3, secondary valve 4, memory spring 5, armed lever 9, spring seat 6, bias spring 7 and adjusting nut 8.Constitute valve body by housing 2, armed lever 9 and spring seat 6.Housing 2 is connected as a single entity by armed lever 9 with spring seat 6, is made by brass material.Memory spring 5 adopts the ti-ni shape memory alloy material.Memory spring 5 is installed in housing 2 inside, is placed in valve rod 3 upper ends, and its two ends are respectively by main valve 1 and spring seat 6 constraints.Bias spring 7 is installed in housing 2 outsides, is placed in valve rod 3 lower ends, and its two ends are respectively by secondary valve 4 and spring seat 6 constraints.Main valve 1 and secondary valve 4 match by two springs and move.Be lower than 70 when spending in water temperature, memory spring 5 is in compressive state, and at this moment, main valve 1 is closed, and the cooling water radiator of not flowing through flows through short circle.When coolant-temperature gage was spent above 70, memory spring 5 beginnings were stretched gradually, and generation power, and this makes every effort to overcome the power of clothes bias spring 7, drives valve rod 3 and moves up, and main valve 1 is opened gradually.When water temperature was spent above 80, main valve 1 was all opened, and cooling water enters major cycle.The heat of the hot parts water that is cooled is taken away like this, sheds by radiator, makes the internal-combustion engine can be not overheated.
If water temperature is lower than 70 when spending, memory spring 5 begins to shrink, and under the effect of bias spring 7 power, main valve 1 is closed fully, and cooling water all enters short circle.So repeatedly, utilize the variation of water temperature, by the cooperation of two kinds of springs, the keying of control main valve, thus guarantee that internal-combustion engine moves under the optimum temperature situation of being everlasting.
